Hi there Im using Xcode 7.3 and connected to the iPhone 6 Plus with iOS 9.0.
Both are already updated to latest versions.
However in XCode > Device I can see my Xcode saying "The service is invalid" "Please check your setup and try again (0xE8000022)." error. I cannot test my apps on this iPhone.
After much search from the Internet, I reboot Macbook and iPhone, deleted derived data etc etc. Problem wasn't resolved. I have tried with iPad with the latest iOS too it is OK. I hav einstalled XCode older 7.x and 6.x versions and the error still exists. I reset all settings and contents and still no help. I cannot isolate the problem to which device because I don't have another Mac / Macbook.
What was the problem ? Please help thanks very much.
